Cooper at3? Loud? If those were loud to you, you will definitely want something like Michelin LTX or something in that category. I've owned multiple sets of Cooper at3, ATP and Zion and road noise was never an issue. But that's just my personal opinion.

My 2017 F-350 came with a Michelin all terrain. After about 500 miles I decided they were coming off. I had them balanced twice and it was still shake rattle and roar. I had great luck with previous LTX Defenders. So I asked michelin to swap them out. They put on the LTX and what a world of difference. Very quiet and a smooth ride. This was a brand new truck.

I've had Michelin LTX M/S2 and Nitto Terra Grapplers on a Tundra, towing 10k. The Michelin never gave me a problem, just liked the look of the Nitto's more. Both sets of Nitto's never made it past 30k miles before 3 out of the 4 started bulging in the tread, causing the truck to shake and have excessive tire noise. On my F350, I have Michelin's LTX M/S2 again, I've learned my lesson with the Nitto's and won't be going back to them. I purchased my truck for towing and though the aggressive tires do look good, they often have more problems than the stock Michelin's so I'll keep my reliability and fugly tires. Stay Michelin, just buy a bigger tire if you want a larger look, keep the quality, quiet, and reliable tire. My $0.02.

On my Excursion I have had Firestone's (blew 2 apart), Goodyear's (had 1 that tread separated) and Michelin's LTX. Michelin's lasted the longest (going on 7 years) and got the most mileage. Way quitter than the rest. Put a set on my Caddy and Challenger. Wouldn't buy any other brand tire.
